[PATCH v4 0/2] arm/arm64: KVM: Optimize arm64 fp/simd, saves 30-50% on exits for non-VHE

2015-07-11 Thread Mario Smarduch
This is a followp to previous iteration but implemented on top of VHE patches. Only non-VHE path is addressied by this patch. In second patch 32-bit handler is updated to keep exit handling consistent with 64-bit code, and nothing has changed. Currently we save/restore fp/simd on each exit, the
